* 3 WATTS REGULATED OUTPUT POWER * 2:1 WIDE INPUT VOLTAGE RANGE * INTERNATIONAL SAFETY STANDARD APPROVAL * FIVE-SIDED SHIELD * HIGH EFFICIENCY UP TO 80% * STANDARD 24 PIN DIP PACKAGE & SMD TYPE PACKAGE * OVER CURRENT PROTECTION
The YKC03 series offers 3 watts of output power from a package in an IC compatible 24pin DIP configuration without derating to 71C ambient temperature. YKC03 series have 2:1 wide input voltage of 9-18, 18-36 and 36-75VDC. The YKC03 features 1600VDC of isolation, short-circuit protection and as well as five sided shielding. A safety designed meet to EN60950 and UL1950. All models are particularly suited to telecommunications, industrial, mobile telecom and test equipment applications.

Note
1. 2. 3. 4. 5. 6. 7. The YKC03 series required a minimum 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, however they may not meet all listed specification. Simulated source impedance of 12uH. 12uH inductor on series with + Vin. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40C. (Ground fixed and controlled environment) M1 version is more efficient, therefore, it can be operated in a more extensive temperature range than standard. Maximum value at nominal input voltage and full load of standard type. Typical value at nominal input voltage and full load. Test by minimum Vin and constant resistor load.
